Nonlinear causality and strong hyperbolicity of baryon-rich Israel-Stewart hydrodynamics
Ian Cordeiro, Fábio S. Bemfica, Enrico Speranza +1
We present the first set of fully-nonlinear, necessary and sufficient conditions guaranteeing causal evolution of the initial data for the Israel-Stewart hydrodynamic equations wit…

Perfect spinfluid: A divergence-type approach
Nick Abboud, Lorenzo Gavassino, Rajeev Singh +1
We present a new formulation of non-dissipative relativistic spin hydrodynamics that incorporates spin degrees of freedom into the divergence-type theory framework. Due to the dive…

Symmetry energy dependence of the bulk viscosity of nuclear matter
Yumu Yang, Mauricio Hippert, Enrico Speranza +1
We clarify how the weak-interaction-driven bulk viscosity and the bulk relaxation time of neutrino-transparent matter depend on the nuclear symmetry energy. We show…
